Electrical impedance tomography (EIT) is a noninvasive measurement technique that estimates the internal resistivity distribution based on the boundary voltage–current data measured from the surface of the conductor. If a thin stretchable soft material with a certain piezoresistive property is used as the electrical conductor, EIT has the ability to reconstruct the position where the resistivity changes due to the inside pressure contact, so that a large‐scale artificial sensitive skin is provided for robotics. First, the different conduction principles and material types of artificial sensitive skins are discussed, which is next followed by the different driving modes and image reconstruction techniques. Then, details on how EIT is used for robotic skin applications are described. Finally, the development trends and future potentials of EIT‐based robotic skins are expounded.

“…In this work, we demonstrate a pioneering study of scaffold-based 3-D cell culture imaging using a miniature-planar Electrical Impedance Tomography (EIT) sensor. EIT is an electrical field based tomographic modality which performs the recovery of the conductivity within interior of a domain based on boundary-applied currents and induced voltage measurements [8][9][10][11]. EIT has been investigated extensively in biomedical imaging [11,12] and industrial process imaging [11,13] with many successful cases.…”

3-D Electrical Impedance Tomography (EIT) is an emerging technique for real-time and non-destructive 3-D cell culture imaging. This paper presents a pioneering study of scaffold-based 3-D cell culture imaging using a miniature planar EIT sensor. A 17-electrode miniature-planar EIT sensor equipped with a regular-shape 3-D printed scaffold was manufactured, modelled and characterized. In addition, an efficient 3-D image reconstruction method based on 3-D isotropic Total Variation and l1 joint regularization were proposed. Numerical simulation on scaffold phantoms and experimental study on time-varying distribution of MCF-7 cancer cell suspension within the scaffold were performed. Both simulation and experiment results suggest that using the miniature EIT sensor and the developed 3-D image reconstruction algorithms are able to achieve high quality, non-destructive scaffold-based 3-D cell culture imaging.

“…Gas–solid bubbling fluidized bed reactors are used in many industrial processes, such as coal gasification, power generation, granulation, and polymerization. To measure hydrodynamic characteristics of gas–solid bubbling fluidized beds, numerous intrusive and non‐intrusive experimental techniques have been developed . The intrusive methods like optical probe, capacitance probe, and pressure measurement are easy to implement but only capable of providing local information concerning the fluid flow.…”

“…The intrusive methods like optical probe, capacitance probe, and pressure measurement are easy to implement but only capable of providing local information concerning the fluid flow. While the non‐intrusive techniques such as tomography can be used to visualize the entire flow field without causing any disturbance to the flow. Compared to other industrial process tomography techniques, electrical capacitance tomography (ECT) shows advantages in terms of fast imaging speed, no radiation, robustness, and low cost .…”

Electrical capacitance tomography (ECT) provides a non-intrusive means to visualize cross-sectional material distribution of gas-solid bubbling fluidized beds. Successful application of ECT strongly depends on the image reconstruction algorithm used. For on-line measurements of bubbling fluidized beds, employing an algorithm that can produce highquality images without extensive computation is necessary. Using the conventional Tikhonov regularization algorithm, image quality in the central area is basically satisfied but suffers from artifacts in the near-wall region. To solve this problem, a similar division operation learned from linear back projection was introduced to modify the conventional Tikhonov algorithm. Both numerical simulations and experiments were performed to evaluate the modified technique.The results indicate that the artifacts can be effectively removed and the reconstructed image quality is similar to Landweber method with dozens of iterations. Furthermore, the modified Tikhonov technique shows high accuracy when obtaining important hydrodynamic parameters in gas-solid bubbling fluidized beds.
